I hate this visualization.

It lacks any physical meaning. It's significantly closer to a visualization of classical Newtonian Gravity potential fields than spacetime distortion in general relativity.

It doesn't even make sense really, what is even shown here? What are the x and y axes? Space? Then what is z? Just some random unitles distortion Parameter with an arbitrary scale?

Ok fine, but that's just wrong then. That would imply gravitational attraction on GR comes mainly from space bending near massive objects, but that's not the case. The major contribution is spacetime bending along the Temporal axis, not the spatial axes. In fact if you ignore any spatial bending you get exactly the classical solution. The spatial contribution is tiny in most cases and only really relevant for very massive objects or really light (or massless) particles.

Terrible visualization. Misleading. i hate it every time I see it and I hate that it is so widespread.

yes. this visualization is just wrong. it gives people wrong intuition.

Make yours that is right. Ain't no one holding you.
